Portsmouth entered administration for the second time just a matter of weeks ago and have been forced to let some of their most talented players leave the club in recent weeks.
Captain Liam Lawrence joined Cardiff, while Erik Huseklepp was noter to leave Fratton Park as the club battle to survive until the end of the season.
Henderson, who has recently become a Republic of Ireland international, has been in superb form for Portsmouth all season and West Ham have moved quickly to seal his signature.
The keeper will initially join the Hammers on-loan until the end of the season and then un the summer a permanent fee will be resolved with Portsmouth.
‘Stephen Henderson will be joining West Ham on loan with a view to a permanent contract," Portsmouth administrator Trevor Birch told portsmouth.co.uk. "We still need money to get past the end of the season.
"It doesn’t just stop then, so I am trying to get in that extra cash which pushes it even further and gives even more time to achieve what we need to achieve.
"I cannot divulge how much we will receive (from West Ham), it wouldn’t be right to. But it’s a significant fee. We wouldn’t be doing it otherwise."
West Ham are looking to secure promotion back to the Premier League and will hope that Henderson can provide support for Rob Green who is currently the number one at the club
